Maybe it should be added a test such as

if (typeof data.query.threads[threadId] !== 'undefined') {




I'd like a way to reproduce this...

I don't remember seeing this again since I reported it, so I can't provide more specific steps to reproduce this.

Anyway, it still seems fragile to access ".content" without checking if "data.query.threads[threadId]" is defined.

There are many places where the code is that fragile. But its important to know what we are fixing.

I vote to this as invalid as it seems to always remain this vague in the future.

I didn't get a screenshot, but I was able to reproduce this (I think, based on the description and my reliance on Google Translate for the Portuguese ;) ) in Firefox. Editing a comment worked fine in Chrome, however attempting to edit a comment on that page in Firefox would refresh the page and delete the entire comment.

Jaime: If you can reproduce it, Firebug or JavaScript error console output is very welcome, plus a link/URL where to reproduce.

Removing "easy" until clear and consistent steps to reproduce are added.

LiquidThreads has been replaced by StructuredDiscussions on all Wikimedia production wikis (except one, which will be done soon). It is no longer under active development or maintenance, so I'm re-classifying all open LQT tasks as "Lowest" priority.
